SEC. 249.91. 2500-2530 18TH STREET AFFORDABLE HOUSING SPECIAL USE DISTRICT. (a) General. A special use district entitled the “2500-2530 18th Street Affordable Housing Special Use District” consisting of Assessor’s Parcel Block No. 4014, Lots Nos. 002 and 002A, is hereby established for the purposes set forth below. The boundaries of the 2500-2530 18th Street Affordable Housing Special Use District are designated on Sectional Map No. SU08 of the Zoning Map. (b) Purpose. The purpose of this special use district is to facilitate the development of affordable housing at the site. The site is owned by the Homeless Prenatal Program (HPP), a family resource center that has been offering comprehensive family services since 1989. With a mission to break the cycle of family poverty and homelessness, HPP’s work focuses on families as they start to ensure they are healthy, stable, and housed. As of February 2021, HPP had a large staff of close to 100, half of whom were former clients or came from the community it serves. HPP has often been recognized for its work in the community. HPP receives generous support from the City and County of San Francisco and has contracts with various City departments, including the Mayor’s Office of Housing and Community Development, the Department of Homelessness and Supportive Housing, and the Department of Human Services. HPP has been located in a building at 2500 18th Street since 2005 and in June 2020 acquired an adjoining lot at 2530 18th Street to further facilitate its mission. Fulfillment of HPP's mission at 2500 18th Street and 2530 18th Street requires a change of the zoning designation for those properties to the Urban Mixed Use (UMU) zoning district, the same zoning designation as the remainder of Assessor's Block 4014.

(c) Use Controls. In this special use district, all newly constructed dwelling units, with the permissive exception of the manager’s unit, shall be affordable to households with an annual income between 0 and 80% of the Area Median Income (as defined in Section 401), for a term no less than 55 years. All applicable provisions of the Planning Code shall continue to apply to this special use district, except as otherwise provided in this Section 249.91.
